Can we get a dialog option to flirt with the Crystal Exarch? [mild spoiler]

That is all but explicitly stated, actually. With Tesleen pointing out her being smitten and being shocked that she'd say it out loud. Her jaw dropping and pouting when Feo Ul stated she'll "always be our side". It's pretty evident Alisaie has a crush on the WoL. I don't think there's any room for misinterpretation there if you've been paying attention.

Again, lot of you seem to be confusing admiration and looking up to someone's as a role model with having romantic feelings. Implying someone is smitten doesn't always mean "having a crush" .
In alisaie case, she just wants to be like us.
Alisaie See's us as family, why you think she trains so hard and so headstrong and trying to fight and get stronger to save people.
Know who else does that? Us, the WoL.

Explain that slight bout of jealousy at Titania's remark and her reaction at Tesleen teasing her for being smitten, then. Not angling for a romantic option, she's a child, but I do think it's adorable that she's got a small crush. Also, you can be infatuated with someone and still want to emulate the better aspects of their personality and admire them. People do this all the time and don't even realize it.
